Question 151991
Find: {{{P(-1/2)}}} if:
{{{P(x) = 2x^4+x^3+12}}} Simply replace the x's with {{{-1/2}}} and evaluate.
{{{P(-1/2) = 2(-1/2)^4+(-1/2)^3+12}}}
{{{P(-1/2) = 2(1/16)+(-1/8)+12}}}
{{{P(-1/2) = 2/16-1/8 + 12}}} Reduce {{{2/16 = 1/8}}}
{{{P(-1/2) = 1/8-1/8+12}}} Simplify.
{{{P(-1/2) = 12}}}
